LOOM FOR WEVING CHENILLE FABRICS.

SPECIFICATION forming part of Letters Patent No. 625,928, dated May 30,1899.

Application filed April 8, 1899. Serial No. 712,201. (No model To alliwhom it may concern.-

Be it known that I, HARRY HARDWICK, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful ImprovementJ in Looms forWeaving Chenille Fabrics, of which the following` is a full, clear, andexact description, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to improvements in mechanism employed in looms forWeaving chenille fabrics, and has for its object to reduce the skillnecessary for the operator and to make the Weaving more rapid, and thusreduce the cost.

It has also for its object to make the setting more certain, thusreducing to a minimum the mistakes in the fabric and increasing the nishand correct design of the fabric.

This invention is a specific embodiment of the invention which forms thesubject-matter of an application, Serial No. 677,123, led April 11,1898, and which invention is therein generically claimed.

I Will noW describe the embodiment of my invention as shown in theaccompanying drawings, in Which- Figure l is a sectional View throughthe shafts and the fabric; and Fig. 2 is a perspective View of a portionof the fabric, the Warp, and the supplemental Warp.

A A', dac., are the ordinary Warps used in Weaving the fabric. TheseWarps are connected in the ordinary manner, one half to one shaft B andthe other half to the shaft B', which shafts are alternately lifted.

J are aseries of supplementary Warps which are connected to the tails b,Which are connected tothe hooks C of an ordinary jacquard, lifted by thegriff or knife D, and controlled by the needles E, operating the cardsin the ordinary manner. The jacquard is so arranged as to operate foreach pick of the chenille tuft or fur, and the cards are so cut that thedesired supplemental Warp or Warps are lifted to form the indicatingdevice for setting the chenille-weft in proper juxtaposition with thepreceding Weft. The operator instead of setting the contiguous weftsmechanically by hand and eye sets each chenille-weft throughout itslength so as to bear a relation to these indicating or supplementalWarps Which are lifted. The supplemental Warps may be a mark of theposition of a given color of the weft thrown, or they may indicate thegiven position of the figure and ground or any desired prearrangedscheme; but in any event the operator has only to locate the prearrangedindicia of the lift with relation to these supplemental Warps Which arelifted.

Of course I do not intend to limit myself to any particular form ofjacquard or equivalent mechanism. A lifterboard jacquard would operateequally Well or a d-obby or any kind of mechanism in which, through, orby the indication of a card or a series of cards any one or a pluralityof these Warps J may be lifted. This is of course a general definitionof a jacquard and also equally applies to a kindred mechanism toaccomplish the same result, and When I use the term jacquardmachine Iintend to include, broadly, any such mechanism as would be covered bythis definition.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-

In looms for Weaving chenille fabric, in combination With the shaft andregular Warp connected therewith, of a plurality of supplemental Warp, ajacquard, and connection loe-A tween said supplemental warp and thejacquard, for the purpose specified.

In testimony of Which invention I have hereunto set my hand, atPhiladelphia, Pennsylvania, on this 7th day of April, 1899.

HARRY HARDVIOK.
